You want to consider serial to Ethernet (for speed) and Multiplexer (for time division) for analysis.

Thanks for the thought, but I was thinking of some sort of very simple and inexpensive system - the complications of ethernet and mux systems are a definite overkill for a relatively small amount of digital I/o over a small distance. <br />

Hi -<br />
<br />
(XP embedded PC)<br />
I am trying to monitor and set various digital inputs and outputs within an electromechanical machine.<br />
<br />
I am at present, using 8 port digital input output boards connected together via an RS485 link.<br />
I have around 60 outputs and 30 inputs which I wish to set and monitor within a short space of time. (around 5mS)<br />
My problem is that the serial data transmission and consequent reception from each board takes far too long. I know I could attach a GPIO device to my PC (XP embedded) and instantly send and receive, but I wish to use some sort of shift register system (similar to boundary scan devices).<br />
Is there any such animal commmercially available?<br />

digital data transmission and reception

Digital forensics encompasses the recovery and investigation of material found in digital devices, often in relation to computer crime. Digital forensics investigations have a variety of applications. The most common is to support or refute a hypothesis before criminal or civil (as part of the electronic discovery process) courts. The technical aspect of an investigation is divided into several sub-branches, relating to the type of digital devices involved; computer forensics, network forensics, forensic data analysis and mobile device forensics. The typical forensic process encompasses the seizure, forensic imaging (acquisition) and analysis of digital media and the production of a report into collected evidence.

Digital Forensics

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

A peripheral device is defined as a computer device, such as a keyboard or printer, that is not part of the essential computer (i.e., the memory and microprocessor). These auxiliary devices are intended to be connected to the computer and used in conjunction with it. Examples of external peripherals include mouse, keyboard, printer, monitor, external Zip drive or scanner, while internal peripherals include CD-ROM drive, CD-R drive or internal modem. Today's new devices, such as tablets, smartphones and wearable computing devices are considered peripherals as they can be connected and used on a computer system. The difference, however, is that these devices can run independently of the computer system.
